Use Case Applications


Cloud and Web 2.0 Environments

ConnectX-6 offers NVIDIA Accelerated Switching And Packet Processing (ASAP2) Direct technology to offload the vSwitch/vRouter by handling the data plane in the NIC hardware while maintaining the control plane unmodified. As a result, significantly higher vSwitch/vRouter performance is achieved without the associated CPU load.


Block-level XTS-AES mode hardware encryption

ConnectX-6 offers a crucial innovation to network security by providing block-level encryption. Data in transit undergoes encryption and decryption as it is stored or retrieved. The encryption/decryption is offloaded by the ConnectX-6 hardware, saving latency and offloading CPU. ConnectX-6 block-level encryption offload enables protection between users sharing the same resources, as different encryption keys can be used.

Networking AI

Machine Learning and Big Data Environments

Machine learning relies on especially high throughput and low latency to train deep neural networks and to improve recognition and classification accuracy. As the first adapter to deliver 200Gb/s throughput, ConnectX-6 is the perfect solution to provide machine learning applications with the levels of performance and scalability that they require.
